Cellular studies, including work involving normal and cancer-cell contexts, require model-specific interpretation. Cells of human origin do not make a study a clinical trial.
No human lifespan benefit follows from these experiments. One source also misnames a residue; sequence identity must be checked before evidence is transferred.
Sources and proposed-mechanism explanation
Telomere biology motivates the hypothesis, but modifying a laboratory endpoint does not establish longer or healthier human life.
